I would say VueTorrent has more features. Yet on Android as it’s not an app you can’t make it open magnet links or torrents when tapping / downloading one.
That would be great to have it as an app or to be able to turn it into a pwa.
+1 that’s what I do at home with my desktop and what is IMHO the best solution.
Yet on vacation I use an old android box with Android Tv (SlimTv) and I have to say it’s nice to have a dedicated interface allowing use of a remote.
I will be off topic as what I am going to suggest is not open source… But I myself looked for a long time what was the best free windows file manager and I settled up on FreeCommander.
By default UI is not nice but it’s possible to make it nice enough.
I use this one mainly because : you can use it for free, dual pan, it remembers tab history between sessions, tabs can be renamed and colored. Hope someone will suggest a good open source one but I don’t think there is any :-/
